PENNSYLVANIA, ASSIGNOR TO HIM- OF SAME PLACE.

Specification forming part of Letters Patent No. 34,032, dated December 24, 1861.

To all whom it may concern:

Be it known that I, THOMAS SHAW, of the city and county ofPhiladelphia, Pennsylvania, have invented a new and Improved Mode of Halt-Cooking SelfiOockingPistols; a-ndI hereby declare the following to be a full, clear, and exact description of the same, reference be ing had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists in adapting a piece of metal to thepawl of the hammer, as hereinafter described.

In order to enableothers to practice my invention, I will proceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of the specification, letters A B 0 represent the barrel, chambtrs, and handle, respectively, ot'an ordinary self-cockin g pistol, with the sides of the handle removed in order to expose the internal construction of the same, of which E is the trigger, and D the hammer, and Ga pawl communicating between the same, the mainspring connected with said pawl G by the stirrup J for the purpose ofp'ulling forcibly down the hammerD upon the cap, and also to replace the trigger E alter firing.

I is a spring pressingon the rear end of pawl F, the opposite end of which fits into notches and revolves the cylinder B, when caused to rise, by pulling the trigger. Said trigger is connected with said pawl by means of screw Nplaying in a slot in pawl F.

P is a spring-catch, the point of which fits into notches'on the back end of chamberB for the purpose of holding said chamber in position with the nipples 0 immediately under the hammer.

M is a pin to be withdrawn when removing the chamberB; K, a piece of steel or arm connected to the pistol by means ofa screw at L, the other end of which looks into the projection or log t on pawl G, the effect of which is to keep the hammerD oftof the cap, and thus preventanyexplosion by accident; and, further, to permit the firing of the pistol by the action of the trigger E alone.

It will be observed that when the pistol is tired the projection t on pawl G is sut'fieiently elevated above the arm K as not to be caught by the same, save after pulling the trigger.

It will be evident that the piece of steel or arm K can be attached to other parts or the pistol than atL, and when combined with the pawl G effects the same object.

What I claim, and desire to secure by Letters Patent, is

The combination of the pawl G with the arm K, substantiallyas described, and for the purpose set forth.
